Got a request for this one. It was designed by Haroldo Gamal and Leonardo Plautz Chocron. The Hell’s Gain is a high gain distortion with an active 3-bad EQ. It’s a big one that ended up with a lot of jumpers, but’s fairly standard with circuit using a bi-polar supply. It’ll fit in a 1590BB or you might be able to squeeze it into a 125B if you turn the board sideways. Enjoy!
